FXLS8471Q 3-Axis, Linear Accelerometer Rev. 3.0 13 June 2019 Product data sheet 1 General description FXLS8471Q is a small, low-power, 3-axis, linear accelerometer in a 3 mm x 3 mm x 1 mm QFN package. FXLS8471Q has dynamically selectable acceleration full-scale ranges of 2 g/4 g/8 g and 14 bits of resolution. Output data 2 rates (ODR) are programmable from 1.563 Hz to 800 Hz. I C and SPI serial digital interfaces are provided along with several user programmable event detection functions that can be used to reduce the overall system power consumption by off-loading the host processor. FXLS8471Q is guaranteed to operate over the extended temperature range of 40 C to +105 C. 2 Features and benefits 1.95 V to 3.6 V VDD supply voltage, 1.62 V to 3.6 V VDDIO voltage 2 g/4 g/8 g dynamically selectable acceleration full-scale ranges Output Data Rates (ODR) from 1.563 Hz to 800 Hz Low noise: typically 99 g/Hz in low-noise mode 200-Hz bandwidth 14-bit ADC resolution: 0.244 mg/LSB in 2 g full-scale range Embedded programmable acceleration event functions Freefall and motion detection Transient detection Vector-Magnitude change detection Pulse and tap detection (single and double) Orientation detection (portrait/landscape) Programmable automatic ODR change using Auto-Wake and return to Sleep functions to save power 192-byte FIFO buffer, capable of storing up to 32 samples of X/Y/Z data 2 Supports SPI interface at up to 1 MHz I C Normal (100 kHz) and Fast modes (400 kHz) Integrated self-test function Integrated temperature sensor with 8-bit output resolution 3 Typical applications Automotive convenience and security Tilt sensing, orientation detection, vibration sensing Navigation applications Industrial IOT Asset tracking Equipment monitoring: vibration analysis, machine healthNXP Semiconductors FXLS8471Q 3-Axis, Linear Accelerometer Medical Patient and activity monitors Consumer devices Wearables Portable electronics 4 Ordering information Table 1.Ordering information Type number Temperature range Package Name Description Version FXLS8471Q 40 C to +105 C VQFN16 plastic, very thin quad flatpack no leads 16 terminals SOT1676-1 0.5 mm pitch 3 mm x 3 mm x 1 mm body 5 Block Diagram Figure 1.Block diagram FXLS8471Q All information provided in this document is subject to legal disclaimers.
